Streams from the Carina progenitor in the evolving and in the non-evolving potential. The streams in the left and centre have the same initial distribution in configuration and velocity space. Those in the right panels have the same initial action-angle distribution as the time-evolving potential (middle panel), but are evolved in a static potential. The colour coding is the same as in the previous figure. The stream-orbit misalignment can be seen by looking at the azimuthal angle of the petals starting from one radial period away from the progenitor, whose position is indicated with a red cross.
